Eh....well while on this subject is that swirl prop still the one to beat? I have a speedster twin 717 and I want max holeshot and acceleration.. I'd be content with a 40-45 mph top speed
On my 97 challenger (single 787), I could only get 44 mph with me in the boat alone. But it had a great holeshot, with or without skier. That was swirl impeller. I got recommendation from Dave at Impros.
